Recently my phone has not been charging properly. When I plug it up to my charger it will rapidly connects and disconnects from the charger despite still being plugged in. Sometimes I'll get the charger in a good position where it'll charge but in a matter of seconds it starts rapidly disconnecting again. It does this with other chargers also, some more than others. At first I thought it might have been my initial charger because the small metal tip at the end is slightly bent, however it's charging other phones with no problem. Could it be that there's something wrong with my phone? I'd love to know how to fix this.
